The present invention relates to a novel class of paramagnetic ion-based contrast i agents of formula, wherein a chelating backbone moiety is highly functionalized by the presence of one or more polyhydroxylated chain, that show a pharmacokinetic i profile analogous to that of the commonly used T1-general extravascular agents but are further characterized by a higher relaxivity. The present invention microlens can be applied in the environment with high temperature, and a passivation layer is not required for the present invention microlens. A controller of the network receives traffic information from nodes and, based on the received traffic information, determines a set of adaptive routing information corresponding to each said node and transmits each set of adaptive routing information to the respective node. The device is capable of determining which sensed emission data corresponds to which vehicle exhaust plume. The enclosed area is associated with at least one reservoir for an irreversible paper destruction product which can be dispersed on the items of value, controlled by a control device. This simplifies the user experience by eliminating the need to go back to a listing page to research products similar to the product whose review is being viewed.
